between front edge of eye and base of caudal fin and over llth 

 scale of lat. line, second over 23rd scale ; first dorsal not quite so 

 high as second, first spine strongest, as high as second and 

 equal to length of head behind middle of eye. Height of second 

 dorsal nearly double length of base. First third of anal anterior 

 to second dorsal ; two fins equally high, base of anal much longer 

 (in some of Dr. Bleeker's specimens first two thirds of anal are 

 anterior to origin of second dorsal). Caudal lunate. Scales with 

 their exposed portion rounded, 21 rows between snout and first 

 dorsal. A short, scarcely pointed scale in axilla. Second dorsal 

 and anal with fine scales. Colour silvery, both dorsals and caudal 

 with dark outer edges.
